yMy invention relates to gas heaters, and more particularly to stoves of the type which include a gas burner and clay elements for radiating heat of the burner flames.

In some types of stoves, lumps of hurried clay or the like are placed loosely in front of and above radiants, such lumps being commonly termed artificial fuel and having the appearance of small lumps of coal, but being of course incombustible. rl`he loose arrangement of the lumps necessitates the employment of grate-like bars in front of the fuel and the radiants to hold the fuel in place, while it is sometimes difficult to effect the proper distribution of the lumps over the radiants in order to produce a desired effect. Furthermore, the lumps frequently become lost.

One objectof my invention is to provide a structure wherein the artificial fuel is formed integrally with the radiants and which nevertheless produces a natural eifect.

Another object of my invention is to provide an improved arrangement of radiants wherein the passages for the gas flames are formed between the walls of adjacent radiants,

Still another object of my invention is to provide a heater of the character referred to of generally simplified and improved form.

@ne form which my invention may take is shown in the accompanying drawing, wherein Figure 1 is a front elevational view of the heater; Fig. 2 is a view taken on the line lI-ll of Fig. 1; Fig. 3 is a sectional plan view of the heater, and Fig. 4l is a view taken on the line lV-IV of Fig. 2, on an enlarged scale. The heater shell or framework comprises a baclwall 5, end walls 6 and a burner plate 7 that are suitably secured together Lin any well-known manner and are supported on the usual feet or legs 8.

To the rear of the burner 9, a series of rectangular openings 11 are formed in the plate 7. These openings 11 serve to receive rectangular extensions or lugs 1S formed on the lower ends of clay radiants 15, to support such radiants against displacement.

The radiants 15 are provided with interfitting tongues and grooves 16 and 17, as

shown more clearly in Fig. 4L, to maintain them in proper relative alinement. The rear or body portions of the radiante not only have the interfitting tongue and groove arrangement but are thickened to such extent that they serve as a backwall. The web portions 18 of the radiants are of reduced width and provided with small projections 19 which become highly heated by the Haines from the burner 9 and facilitate the radiation of heat, The portions 18 are spaced apart such distance that vertical passages for the flames are provided between the various radiants, as distinguished from the common practice of making the radiants or burner tubes hollow and eecting radiation through reticulated openings formed in such tubes.

irregularly-shaped lugs 2O are formed integrally with the radiants 15 and constitute the front faces thereof. rFliese portions 2O are colored to give them the appearance of fuel. The irregular shape of the elements 2O permit the radiation of heat therebetween and they will become heated to an extent that they will have the appearance oi glowing coals. Furthermore, they are of such size relative to the webdile portions 1S of the radiants that such portions 18 are largely concealed and the elements 2O have the appearance of loosely piled fuel. lf desired, additional lumps of fuel may be loosely piled upon the uppermost elements 20.

In order to further maintain the radianls 15 in place, l provide holes therein for 'the reception of a. tie rod i9 which extends through the radiants and through the end walls 6 of the heater. By removing one of the nuts on the ends of the rod 22 it may be slid out of place to permit removal of the radiants.

From the foregoing it will be seen that l not only provide a heater of the artificial fuel type wherein the artificial elements are rigidly maintained in place, but an improved type of radiant which need not be made hollow and consequently of delicate structure as in the case of ordinary burner tubes, the passages for the gas flames being provided between the various radiante as above er:- plained. Furthermore, the radiants are securely held against displacement either with respect to one another or with respect to the frame of the stove.

I claim as my invention 1. A gas heater comprising a supporting framework, a burner extending across sani framework, and radiants mounted on said framework above the burner, those portions of the radiante immediately above the burner being of reduced thickness in a direction iongitudinally of the burner, to provide vertical gas passages between the radiants.

2. A gas heater comprising a supporting framework, a burner extending across said framework, and radiante mounted on said framework above the burner, those portions of the radiants immediately above the burner being of reduced thickness in a direction longitudinally of the burner, to provide vertical gas passages between the radiants,`and the radiante having irregularly-shaped protuberances upon their front faces and forwardly of said reduced portions.

3. A gas heater comprising a supporting framework, a burner extending across said framework, radiants mounted on said frameA work above the burner, those portions of the radiants immediately above the burner being of reduced thickness in a direction longitudinally of the burner, to provide verticzl gas passages between the radiants, and radiating tips carried by the radiants and extending into the said passageways.

4. Heater structure comprising a supportin frame, radiants carried by said frame in si( eby-side relation, means between the sides of the radiants for effecting interlocking thereof, and means on said radiants for effecting interlocking engagement with the framework.

5. The combination with a heater, of a plurality of radiants therefor each having artilficia'l fuel velements formed on the front sides thereof, the said elements being connected to their respective bodies by portions of reduced width and such portions of reduced width being spaced apart to provide gas passages.

6. The combination with a heater, of a radiant therefor having artificial fuel elements formed on the front side thereof, the said elements being connected to the body portion of the radiant through a reduced portion thereof.

7. The combination with a heater of a radiant therefor having an upwardly-extending portion and a portion extending in a direction generally transverse to the first-named portion, and artificial fuel elements formed on the exposed sides of said element.

Y8. Heater structure comprising a framework, and clay elements supported by said framework, the rear portions of said clay elements being of sufficient thickness that they together form a backwall and the front portions thereof being spaced apart and of reduced horizontal dimension in order to function as radiants.

9. Heater structure comprising a framework, clay elements for said framework .having enlarved rear portions which together serve as a backwall and having reduced intermediate portions spaced apart to function as burner tubes and also having enlarged protuberances extending outwardly from said reduced portions.

it). Heater structure comprising a framework including a burner plate having a burner opening therein, clay elements supported by said framework and plate, the rear portions of said elements being of suiiicient thickness that they together form a backwall, and the front portions thereof being spaced apart and of reduced horizontal dimensions in order to :function as radiante, and means for effecting interlocking engagement between each of the lower ends of the thickened portions of said elements and the plate.

l1. Heater structure con'iprising a framework including a burner plate .having a burner opening therein, and a series of openings disposed rearwardly of the burner opening, clay elements supported on said'burner plate and having protuberances extending into the said series of openings and forwardly extending projections disposed over the burner opening.

l2. Heater' structure comprising a framework having a burner plate, a burner disposed below said plate adjacent to the forward edge thereof, clay elements disposed in side-by-side relation upon said burner plate and having forwardly extending projections disposed above the burner, and means for effecting interlocking engagement between the lower ends of said elements and the burner plate lat points rearwardly of the burner.

In testimony whereof I, the said 'Winnaar L. SHARP, have hereunto set my hand.
